AUDI A6 2.0 2016

🚨 What to check before buying

Overall risk score: 10/10

Serious risks

• DPF clogging (short trips): Like all modern diesels, short city trips clog the DPF. Highway driving cleans it.
• EGR valve: EGR valve can accumulate carbon over time. Cleaning usually sufficient.
• AdBlue injector crystallization: SCR injector can crystallize urea deposits, causing warnings and limp mode.
• Timing belt replacement: Planned maintenance — belt every 210,000 km. Not cheap but infrequent.
• Car is 10 years old — some age-related maintenance expected (seals, suspension components)
• Higher mileage (190,772 km) — check for timing system condition, turbo health, and suspension wear

Additional notes

• Audi A4 2.0 TDI very common in Bulgaria (3000+ listings). At 200k+ km: oil pump failure (EA288), DPF, AdBlue system, and S-Tronic mechatronic are all potential repair items.
• Audi A8 diesel (890+ listings in BG). Air suspension failure is almost guaranteed at 10+ years. Combined with timing chain, AdBlue, MMI electronics, and luxury car labor rates, total cost of ownership is very high.
• Diesel car from before 2018 with very low mileage suggests city-only use — DPF is likely clogged or has been removed (illegal). Check DPF status and EGR condition.
• Audi Q7 diesel (245+121 listings, avg 170-176k km, €35k) — full-size SUV with full-size bills. EA897 3.0 TDI timing chain service due (€3000-5000), air suspension compressor and bags wear at this mileage (€4000+), AdBlue system failures (heater, injector, tank). Brake discs alone are €600-800/axle.
